Mesh * createMeshFromResource(const std::string &resource)
Load a mesh from a resource that contains a mesh that can be loaded by assimp.
Definition of a triangle mesh By convention the "center" of the shape is at the origin. For a mesh this implies that the AABB of the mesh is centered at the origin. Some methods may not work with arbitrary meshes whose AABB is not centered at the origin.
